Topic: Canon 50D (Read 398502 times)

i own a 60D and 5Diii. Unfortunately the 60D's RAW capabilities are not that good due to slow SD card writing.

Just as an opinion, would you suggest getting a 50D as a "cheap" RAW B-roll camera as company for my 5D as the main camera? Of course, cheap is relative . Since i don't own a 50D yet, do the two combine good together, feature wise?

I love the 50D. Non crop max resolution is: 1584 X 1058 continuous and in crop 2000(1920) x[1080 2:1/ 980 continuous . If that works for you go for it.The footage graded and with a LUT reminds me of super 16mm footage. I wouldn't consider the footage from the 50D quite as perfected as the footage from the 5Diii. But everyone has a different opinion.

I loaded the latest build 3.27.14 and the first thing I noticed is that I was able to set the Shutter to 1/48 which had been an issue for me in the past. I saw that the resolution had increased a bit to 1568x882. I'm using a Komputerbay 32GB card. I did notice that it takes longer for recording to actually start now.

The 1st time I tried to record it lasted just about a minute and then the camera reported 1 skipped frame and locked up, so I had to remove the battery. After that it recorded for 5 minutes straight with no issues whatsoever.

I noticed that at the start of a new recording the 3rd time the little Green Camera icon flashed Red and Yellow a few times before staying solid green as it started recording.

I also noticed that the remaining free Storage space doesn't update after a new recording until I turn the camera off and back on.

This is MLV Rec on1568x882 Global Draw on all modesZebras onSpotmeter onWaveform Small onFPS Override on 23.976 (Exact FPS)Expo. Sim onLV DIGIC Peaking onFile Manager onMLV Play onPicture View on Camera temp was at 48C after all the recording.

Alright, I think I've determined that live view juddering and frame drops while changing aperture while recording is a hardware limitation and that the 50D is essentially useless for manually riding the exposure with a EF/EF-S lens and that it's only possible with a manual lens with aperture ring. If this is wrong then someone please correct me.

That aside, I notice in the stable build and in a certain 3rd party fork that I won't mention (the last time I did, the thread got wrongly moved to an area of the forum I have no access to) I can adjust the aperture (or other exposure settings) while recording video (H264). This doesn't seem to be possible in the latest nightly, using the camera wheels do nothing other than change the indicated value on the top LCD. Exposure override is enabled and exposure lock isn't on. If I enable Av adjustment on the joystick, the camera locks up if I attempt to adjust them while recording. If I reboot the camera and try to use the joystick again to say set the ISO, sometimes the display corrupts and flashes and the camera requires a reboot again. If this is all unclear I can take a video of the problem.

Aside from that, very happy to see the 50D back in the mainline nightly builds! I have a variety of lenses and CF cards for any testing required. Fastest is a Komputerbay 64GB 1000x.

So I've also got the above issue with not being able to adjust aperture and so on with the wheels while in Liveview. I have to go to the exposure page of ML to adjust.

Also I now have VERY pink frames while processing the MLV files with raw2cdng. I did now have this before with a third party modification I will not mention here. Does anyone else have this?

For me I will not be switching to Nightly just yet.

Glad to hear it's not just me. Could you confirm that if you adjust the aperture while in live view (in a version that does let you do it) that the live view freezes briefly which also affects recordings? I've still not had any confirmation of this from anyone.

@far.in.out That fixed it, thank you!

@rguk Would have to try if I get the same behavior. Will report back asap.

Crop mode: press the "5X" zoom-in button. Depending on your preview settings for RAW recording, you may see a black and white ML preview, which shows the full extent of the recording but has a slow refresh rate, or you may see a Canon preview, which refreshes fast but only shows a portion of what will actually be recorded.

As i understood, i will not be able to see the real angle of view in crop mode?

Well.. not quite...you will see part of what ( a large percentage of what) you are filming in the viewfinder but the area that you are filming/ recording will be somewhat greater than the area that you are seeing in your viewfinder. Particularly width wise. Similar to a lot of film cameras that would give you about 90-99% of your picture in the viewfinder. In other words; in crop mode the area that you are filming is slightly greater than what you see in the viewfinder

The 1st time I tried to record it lasted just about a minute and then the camera reported 1 skipped frame and locked up, so I had to remove the battery. After that it recorded for 5 minutes straight with no issues whatsoever.

I have same problem on my 50D. Right now Im on nightly from 22.3. and it was same on older build from beginning of March. I will try it again on latest nightly build soon and report back. I get those "1 skipped frame lock-ups" very often. About 1/4 of all cases and it is very annoying as you must turn it of, remove battery, turn on (then it skips modules) so you have to turn off again and then on. Now I have next try ) Sometimes problem repeats couple of times. This drives not only me, but even my unpatient wife very CRAZY :-)Scenario is always the same. I start recording. 50D starts record session and displays indicator on screen. Now it either continues smoothly without any problem, OR it indicates 1 skipped frame and immediately crashes. Now you are not able to stop recording or do anything else... RAW file is not saved. This happens in both full sensor mode and in crop mode.

Im set like this:This is RAW Rec on1568x882 Global Draw on all modesZebras onSpotmeter offWaveform offFPS Override on 23.976 (tried both Exact FPS and optimize for Low Light)Expo. Sim onFile Manager onRAW Play on

So now we know that problem is in both MLV and in RAW recorder. What I want to try (if this will still happen on latest build) is to set frame skipping to be allowed. Now I have it set to stop on skip.

Let me know if you need any further info or something to try... I will update in next few days.
